Observations of quasar host galaxies with laser guide star AO

Abstract

We report on observations of two quasar host galaxies made with the Lick Observatory adaptive optic system using a laser guide star tuned to the wavelength of the sodium D lines. A brief outline of the system is given, and a description of its performance when obtaining science data. We discuss techniques for obtaining calibration of the point spread function and the analysis steps required to obtain useful scientific results. We present H-band images of quasar host galaxies made with the system. Estimates of the host galaxy magnitudes and central black hole masses were made from these data. These are the first observations of quasar host galaxies with a sodium laser guide star.
